AMES, Iowa -- After four days of racing the Iowa State University solar car
is in fifth place.

Bright morning sunshine greeted the Iowa State solar car
team members in Charlotte, N.C., as they set off June 23 for the fourth day
of Sunrayce 99. But the clouds were soon back, making the day another
endurance test for participants of Sunrayce 99.

Iowa State's PrISUm Phoenix was the 10th team to complete the 150-mile race
route, doing so in 6 hours, 25 minutes and 2 seconds (6:25:02) for an
average speed of 23.29 mph.

The first team to complete today's leg (Charlotte, N.C., to Clemson, S.C.)
of Sunrayce 99 was Messiah College, which finished the course in 5:09:20,
for an average speed of 28.99 mph. The next three finishers were Kansas
State University, which finished in 5:33:47 (26.87 mph); University of
Missouri-Rolla, in 5:34:36 (26.80 mph); and Queen's University in 5:40:45
(26.32 mph).

Iowa State began the day in 4th place overall.

"We had some good sunshine until 11 a.m. or noon. Then the clouds rolled in
so we decided to slow down and conserve energy," said Team PrISUm Strategy
Leader Jeff Lanning. "But later in the day, the sun came back out and we
decided to make a run for the finish line to recharge our batteries."

Tomorrow's 134-mile leg of Sunrayce will be from Clemson, S.C., to Atlanta.
Friday will be a rest day for all solar car teams. The race will resume on
Saturday, June 26.

Sunrayce 99 coincides with the week of the summer solstice. The 1,424-mile
race began June 20 in Washington, D.C., and ends June 29 in Orlando, Fla.

Sunrayce is an ongoing educational program that culminates in a biennial
cross-country race of solar-powered cars. The program is open to colleges,
universities, trade schools and other post-secondary educational
institutions.
